The train is an example of the amount of towing power that can be achieved with an electric motor
I’m pretty sure the poster you were responding to was talking about towing range, not raw power.

I've been considering a steam powered car. Sounds like coal will be getting even cheaper than it is now.

I'm looking forward to it. They are mush simpler and should have fewer problems than our relatively complex ICE powered vehicles.
It will take a while. Our power grid isn't ready. You're talking about a massive energy transfer from gas, that has to be delivered to our garages instead via power.
Also raw materials--those batteries are made up of some fairly precious stuff.
Would be nice to see vehicles start to be more practical and less "lifestyle projecting." It's always bugged me that we choose to polish these things to a high mirror shine, only to have them hurtle through the world. It's built-in obsolescence.

You do realize that technology changes and improves rapidly, right? You realize that battery charging times have already improved dramatically , and will continue to do so, right?
I don't think anyone is denying this. However, ICE vehicles have range, refueling and infrastructure advantages now and for the foreseeable future. The current electrical grid does not have the capacity for tens of millions of electric vehicles (especially in high population areas that already have capacity issues).
Even if these can be overcome (or the gap appreciably reduced) you still have limitations. Electric vehicles have inherent disadvantages in colder climates.

Bigger question is will I have a personal daily driver in five or ten years from now?
I doubt it. In 2029, our robotic driving overlords will probably dispatch an autonomous vehicle to my door and it will take me where I need to go.
The actual amount of time I use a vehicle during a day is rarely over 10% of the time in a day.
90% of the time my daily driver is a sitting non-productive asset
This.
In a not very distant future, self driving cars will make automated transport cheap and efficient. Families may own a single car for everyone to use or, more likely, services similar to Uber/Lyft but with automated cars will be used a lot more.

The work required to make that happen is beyond imagination.

think putting a diesel generator in an “electric car” would kind of defeat the purpose.
That's basically what a Chevy Volt was except it was gasoline powered. But then they went out of production. Wasn't as efficient as the way Toyota did the hybrid system in Prius.
I think various versions of weak to moderate hybrids will become more mainstream in the next 10 years. The new Lincoln Aviator has hybrid system that combines a turbo V6 with a electric motor between the engine and transmission. Total output is 494 hp and 630 lb-ft torque. But not really made for economy.

Within ten years electric autonomous vehicles will really start to disrupt the market

quote:FWIW, it's a lot more than just the gas. No oil changes, no changing transmission fluid every however often you have to do it. None of that.
I'm not opposed to them either but it would take me a hell of a long time to recoup the extra cost (if i ever would) over the $75/month I spend on gas.
The only routine maintenance needed are tires and washer wiper fluid...that's it.
When you factor in all of that for total cost of ownership, a $40k car after 5-7 years I'd guess cost about the same as a $25-30k car.

quote:Women run out of gas every single day in their cars in America right now. You are right that they will forget to plug in, that's a given. But I'd argue the convenience of plugging in in your garage vs going to a gas station to buy gas, they'll likely be running out of battery less than they'll run out of gas if we're talking about every day local driving.
There will be a lot of people (women) who forget to plug in every time they pull into the garage at home and find themselves leaving work one day with 2% charge left on their car.

As for plugging in at the grocery store, would you leave a gas pump and fuel line hanging from your car out in public for 30 minutes to an hour unsupervised? I wouldn't.

What’s funny is I have a 2005 hybrid. It’s electric and gas and my tag is more than a gas only engine which to me is bullshite!

I can see system where something hanging from the bottom of the car will come in contact with a power source on the road / or parking spot. This would power/charge a car. Kind of like the 3rd rail in a subway station.
Wireless could be an option further down the road.

How far away are we from the average consumer taking a hard look at an electric vehicle, or e-cars just outright being the norm?
It's 2019. Average people are buying Teslas now. Every major manufacturer has at least one EV on the market.

We have plenty of oil to last us 100 plus years.

Batteries don’t have the necessary energy density

That just won't happen. The only time you should EVER have to stop at an actual recharge station would be if you go on a long road trip. Otherwise, your vehicle will recharge overnight in your garage and you leave the house with a full charge every morning. You will spend far less time "filling up" with an EV than you do with a gasoline vehicle.
recharge times are far too long

quote:There are many new chemistries being developed. Don't you think it's only a matter of time before one or more of them become suitable for commercial applications? We may be approaching the limits of lithium batteries, but that's the way technology works. We squeeze every bit out of a technology until something comes along to replace it. What makes you think we are at the end of battery development? Especially considering how much money there is to be made by continuing to develop new tech?
Energy density of lithium batteries today have changed very little in the last 15 years, they are cheaper but the fundamental chemistry is still the same. There are other chemistries but they rely on extremely toxic, unstable, or commercially unsuitable designs. Charging times are a matter of techniques like pre-cooling the battery packs and better algorithms to force feed the batteries but there are still limits due to the chemistry.

This is also improving all the time, but the biggest folly with this argument is you're thinking that you'll be stopping for a long recharge as often as you currently stop at a gas station.
Unless you need a full charge, each stop is 10 minutes generally speaking.
I see charges getting up over 500 miles/hour but it slows down a ton towards the end if you need to fully charge.
When you route trips, you generally charge for 10 minutes and that's it.

quote:At the end of an automotive battery's life, it can be repurposed for home energy storage. You can probably get another 10-20 years of life out of them this way since you don't need 100% capacity. And in a few years home energy storage is going to be as big a deal as EV's are right now.
Wait till we get the hurr durr of having to figure out how we manufacture and later dispose of hundreds of millions of automotive grade batteries.
